Fases de la Lluna

The phase of the moon where it is not illuminated by the sun and is invisible from Earth.

An eclipse occurs when the Earth casts a shadow on the Moon.

The lack of a protective atmosphere on the Moon makes it vulnerable to impacts by meteoroids and asteroids, creating craters.

The Moon orbits the Earth and its different positions relative to the Sun and Earth create the phases we see.

A map or representation of the Earth's surface, usually on a flat plane.

Meridians and parallels are imaginary lines used to locate points on the globe. Meridians run North-South and parallels run East-West.

The meridian that passes through Greenwich, England, is often called the prime meridian and divides the Earth into East and West hemispheres.

The Equator is a parallel that divides the Earth into Northern and Southern hemispheres. It is located at 0 degrees latitude.

Latitude is the angular distance, measured in degrees, north or south of the Equator.

Longitude is the angular distance, measured in degrees, east or west of the prime meridian.
